### Altering and locking features of the network design

#### Purpose

Iterations are virtually unavoidable when designing a network. After each calculation of a design, verification and validation is necessary to optimize the result.

#### Workflow

The Comsof Fiber Integration Module provides the possibility to make adjustments to the calculated design by altering certain features on the different network layers. Thus, you can, for example, move certain structures or equipment, redraw trenches or drop trenches, reshape clusters etcetera. After these adjustments, you can have the design recalculated. However, to make sure that these adjustments are not overwritten during the calculations you have to lock all the features that are affected by the changes that you made.

You can find extended information on these features in the Comsof Fiber Manual. Interesting topics to refer to are Chapter 5 – Calculation and Fine-Tuning, Clustering, Forced Equipment.

To change, for example, the shape and size of a drop cluster, take the steps below:

1. Select the cluster feature polygon by clicking it on on the map.

   The Details panel shows the information about the selected feature.

2. Click the Edit button from the toolbar at the top of the panel.

   The IN Drop Cluster dialog box opens.

3. Make the desired adjustments.

   1. The Update Geometry button allows you to change the shape/position of the feature on the map.

      When you click it, white squares are displayed representing the point or the node of a line or polygon. By changing these points you can alter the feature. Click Done to return to the dialog.

   2. Tick the Locked check box.

      This attribute guarantees that the cluster is not altered when you recalculate the design afterwards. In the dialog other attributes are listed. You could also set the values of (some) of those if appropriate.

4. Click Save when all the changes are complete.

   The dialog closes.

5. Repeat the steps above for the different cluster polygons that need adjusting.

#### Locking an entire layer at once

To avoid that you have to go about locking large numbers of features of the same type, the Comsof Fiber Integration Module provides the possibility to lock/unlock an entire layer at once.

To do so:

1. Go to the Layers panel.

2. Click the padlock button () from the toolbar at the top.

   The Lock Features dialog opens.

3. From the list select the layer that you want to Lock or Unlock.

4. Click the indicated button.

5. Close the dialog by clicking the X button in the dialog title bar.
